Pope Shenouda III
Through fasting Yogis were able to discover some of the strength of the soul.
Hampered by one's care for the body the strength and power of the soul have only been discovered through fasting.
Hindus believe that the supreme state of Nirvana or the release of the soul from the body to become one with God can only be accomplished through intense asceticism, abstinence, and fasting.
Thus we see that even a soul that is far from the work of the Holy Spirit, and free from bodily desires and its control, becomes a strong, able to attain some of its original natural potential. How much more so is the soul, which is in communion with the Spirit of God?
